Phase unwrapping is so important that it determines the precision of the DEM of INSAR directly. To improve the precision of phase unwrapping, a new method based on method of Goldstein is given. Qualification data are produced with the inconsistent points to determine the optimal integral path. With this method, the error is restricted in a small area, the operation keeps fast, and the precision is improved. With the help of simulation of INSAR data, the capability of the two methods is compared. The result of phase unwrapping of ERS1/ERS2-SAR data shows the capability of the new method.
